[IUFRO Div 8] ITMN Online seminar with Ana Bastos February 15 (4 pm CET)

Dear all, The International Tree Mortality Network, an initiative of the IUFRO task force on monitoring trends and patterns in global tree mortality, continues the online seminar series join on *February 15, 4 pm CET*, with: *Dr. Ana Bastos* *Title: **Climate variability, extremes, and attribution of high-impact ecological events: challenges and ways forward* _Abstract:_ Climate and weather extremes impact tree functioning directly and can further trigger forest disturbances, thus affecting forest functioning and dynamics over periods much longer than the extreme per-se. With increased frequency or intensity of extreme events projected in the coming decades, extreme events might cluster in periods shorter than recovery times, thereby amplifying impacts and potentially inducing degradation and mortality trajectories. Understanding the links between atmospheric variability controlling extreme event occurrence and downstream impacts on forests is, therefore, crucial to: (i) separate trends in disturbance/mortality events due to natural vs. anthropogenically forced climate variability, (ii) improve process understanding about the drivers of high-impact ecological events and (iii) increase the robustness of future projections of forest dynamics. _Bio:_ Ana Bastos is the Lead of the Climate-ecosystem-disturbance interactions group of the Max Planck Institute of Biogeochemistry. She specialises in climate-ecosystem interactions with an emphasis on the inter-annual to long-term variability in the global carbon-cycle. *Please register for the Zoom Webinar: * https://zoom.us/webinar/register/4216438940390/WN_LtlBqI-FQCCj2nsaV82OGQ Note that the talks might be recorded. * * *Previous seminars:* Seminar # 1: Matt Hansen - Global forest monitoring using satellite data https://youtu.be/snUSGNb9bAQ Seminar # 2: Flavia Costa - Tree mortality in the Amazon across local hydrological gradients: how water table depth may save or condemn trees as climate changes https://youtu.be/5wmzX9ldn4Q Seminar #3: Belinda Medlyn - Tree mortality in Australian ecosystems: past, present and future https://youtu.be/T6S9VKklbyc Seminar #4: Nate McDowell - Rising tree mortality in the Anthropocene https://youtu.be/vdAXQ8CibKA Seminar #5: Lisa Hülsmann - Tree mortality modeling – a tool for ecological inference and a challenge for projecting forest dynamics https://youtu.be/Yzsa0p7lq7c Seminar #6: Craig D Allen - The global emergence of hotter-drought drivers of forest disturbance tipping points https://youtu.be/5NlkIQOzl2Y <https://www.youtube.com/watch?v=5NlkIQOzl2Y> Seminar #7: Yude Pan - Impacts of disturbances on leaf area index and productivity of terrestrial ecosystems https://youtu.be/mhHxGPVZXXE <https://youtu.be/mhHxGPVZXXE> Seminar #8: Viacheslav Kharuk - Conifer decline and mortality in Siberia https://youtu.be/2X4ZoUQa8jA <https://youtu.be/2X4ZoUQa8jA> Seminar #9: Barbara Bentz - Recipes for Climate-Induced Bark Beetle-Caused Tree Mortality https://youtu.be/ddjMbYvuX6I <https://youtu.be/ddjMbYvuX6I> *Visit us at:* https://www.tree-mortality.net/ https://www.iufro.org/science/task-forces/tree-mortality-patterns/ --- Dr. (habil.)
